That conversation tells me nothing at all. In some his posts r0ach claims he does not give a shit to alts and in this OP he says he is alt trader.
Most alts are just flat out scams. There's not really a single one on Poloniex that has any fundamentals right now besides Monero. Zerocash has so many drawbacks that it's actually worse than Cryptonote, but Roger Ver wants to pretend that isn't the case. There is no other good option for anonymity. There is also no right answer in the Bitcoin scaling debate. Raising the block size is a risk, just like hard forks are a risk due to rough consensus attacks, and legality of exchanges possibly being required to carry both coins (2 versions of Bitcoin) if such a thing is done. If I deposit a Honda stock with you, you can't give me back a Toyota stock, and a hard fork is the exchange itself making that choice, while a soft fork can technically exempt the exchanges.
Building a 2nd tier system to expand TPS on top of Bitcoin is actually a logical decision, so is the decision to only do soft forks in an attempt to avoid rough consensus attacks where exchanges might be required to carry two different versions of Bitcoin. On the other hand, it's not really possible for the 2nd tier scaling solutions to be as secure as the on-chain solutions, so there should exist another coin for the big blockers to attempt their way instead of trying to fork Bitcoin. Forking and big blocks are risky, and Bitcoin isn't about risk, so that task should be taken by an altcoin.
Monero is currently the best option for "big blockers" that exists due to the anonymity solution already requiring on-chain transactions anyway, plus having a dynamic block size. I'm honestly surprised there hasn't been a large divergence of small blockers staying on Bitcoin and large blockers going to Monero sooner (maybe it will happen after wallet). Both scaling options are IMO valid options, and both options have positives and negatives.
The main Bitcoin developer that exists right now has actually worked on Monero, so it's a lot less of an altcoin than most altcoins:
